Specification of Letters Patent.

Patented March 20, 1906.

Application filed-April 20. 1905. Serial No. 256,646.

To all whom it may concern..-

Be it known that I, HUGH BEATTY, a citizen of. the United States,residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inWindow-Cleaners; and I do declare the following to be a folk-clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to'make and use the same, referencebeing had to the accompanying drawings, and to the figures of referencemarked thereon,'which form a part of this specification.

This invention relates to an improved device for cleaning the outside ofcar-windows of frost and snow, and is particularly useful to motormen inthe winter season; and it consists in the certain details ofconstruction and combination of parts as will be fully describedhereinafter.

In the accompanying drawings, Figure 1 is a front elevation of astreet-car window, partly in section, the same being provided with myimproved device, which is constructed and arranged in accordance with myin vention. Fig. 2 is a side sectional elevation of the same, the saidsection being taken on the line y y of Fig. 1 Fig. 3 is a horizontalsectional view on'the line w (l; of Fig. 1.

To put my invention into ractice, and thereby provide a device where ythe motorman of a street-railway car may easily remove frost or snowfromthe front or outside of the WlIldOW- lass 1, I arrange at either side ofthe sash vertical box-frames 2 for incasing'suitable moving weights 8.Attached to these boxes are guide-strips 3, the one par-' allel to theother, and in which 'a sliding bar 4 is arranged in a horizontalposition, the said bar being formed with end slides 5, capable of beingmoved the length of the guide-bars 3. Mounted upon the horizontal bar 4are two bearings 9, in which levers 10 are pivoted by means oftransverse pins, the said levers being provided at their outer ends withweights 11, the inner ends 13 being bifurcated to receive a rectangularscraper 12, which is held in lace by set-screws 14. Attached to the Sll(es 5 of the bar 4 are cords 6, which pass over pulleys "Z, located atthe top of the boxes 2, the other ends of said cords being connected toweights 8 in a manner that will keep the scraper 12 in its elevatedposition atthe top of the window-sash. Attached to the inner ends of thetwo levers 10 are cords 15, each of which is bifurcated at its upperend, one terminal being attached to the scraper 12 and the other to thelever 10, the lower end of the cords being threaded through openings 16,formed in the lower rail of the window-sash.

In operation when the device is at rest the scraper 12 is held free fromthe glass by the weights 11 on the ends of the levers 10, and

the window may be opened or shut without interference. If it is desiredto scrape the glass 1 and clear the same from snow, &c., it is onlynecessary to draw the cord 15 inward. This will bring the scraper 12 incontact with the lass and move the said scraper downwar( along thelength of the same. When the cord 15 is released, the weights 8 willreturn the scraper 12 back to its normal position.

It is obvious that various sli ht modifications and changesniay be madein the details of construction without departing from the spirit of theinvention. Therefore I do notwish t0 confine myself to the exactconstruction shown and described, but wish to claim all such modifiedforms as would come properly within the general scope of the invention.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. An apparatus for cleaning windows, comprising guidc-stripsattached tothe Window-sash, vertically-movable slides arranged between the sash andsaid strips, weights arranged in the sash and connected to said slides,a horizontally-disposed bar carried by said slides, a plurality ofbearings mounted on said bar, a weighted lever pivotally mounted in eachbearing, a scraper carried by said levers and cords connected to saidscraper and extending through holes into the ba' oi the window-sash.

2. In an apparatus for cleaning windows, the combination with balancedslides mounted to move vertically on the \viiulozv-i'iww a hm carried sysaid slides and extending In testimeny whereof Iaffix-my signature @Le'w'mdow, a counterwelghted 1n presence of two wltnesses.
